4.4.5 Firing Rate Dependent and Fuel Specific Limit Values/Limit Curves
The burner firing-rate value or some other measured quantity is supplied via analogue input 4
or via LAMTEC SYSTEM BUS. Instead of fixed limit values you can enter fuel-specific curves
with 2 up to a maximum of 8 checkpoints.
Possible combinations:
either
• 2 fuels with 4 limit curves / limit values per fuel
• 4 fuels with 2 limit curves / limit values per fuel
For details see supplement to the operating instructions for the optional "Display and operat-
ing unit”
